Product details
Overview
MP6650GJS-0000-P from Monolithic Power Systems is a single-phase BLDC motor driver IC with integrated Hall-effect sensor, power MOSFETs (740 mΩ total RDS(on)), and reverse-voltage protection. It delivers up to 2 A output current, operates from 3.3 V to 18 V, and features configurable speed curve, soft on/off phase transitions, and rotor lock detection via open-drain FG/RD pin - used in CPU fan control for servers and desktop PCs.
For engineers reviewing the MP6650GJS-0000-P datasheet, MP6650GJS-0000-P pinout, MP6650GJS-0000-P application, or MP6650GJS-0000-P equivalent, key selection criteria include Hall-integrated single-phase drive capability, TSOT23-6-SL package compatibility, 26 kHz fixed switching frequency, input reverse protection, and programmable current limit (0.7–2 A) for thermal and acoustic optimization in compact fan modules.
Technical Context
The MP6650GJS-0000-P implements a Hall-sensor-based commutation controller with automatic phase-lock detection between winding BEMF and current zero-crossing. Its internal half-bridge drives a single-phase BLDC motor using PWM input (2–100 kHz) to linearly modulate output duty cycle while maintaining fixed 26 kHz switching frequency above audible range.
It integrates full protection logic: input OVP (19.2 V), UVLO (3.25 V), thermal shutdown (150 °C), rotor deadlock detection (0.6 s timeout), and reverse-voltage protection. Speed feedback is provided via FG/RD open-drain output with selectable 100% or 50% Hall frequency division and programmable starting duty (via register 0x14).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.3 V to 18 V - supports wide-range DC supply without external LDO; includes reverse-voltage protection eliminating need for external series diode. |
| Output Current Limit | Configurable 0.7 A / 1.1 A / 1.6 A / 2 A - set via SUCL register bits to match motor inductance and thermal constraints in fan applications. |
| Switching Frequency | Fixed 26 kHz - avoids audible noise while enabling efficient magnetics and low EMI in compact fan PCB layouts. |
| Hall Sensor Sensitivity | Operate point ±1–2 mT, hysteresis 2–4 mT - enables reliable rotor position detection across temperature (−40 °C to +125 °C junction). |
| Soft Transition Angles | Soft-on: 22.5° at 100% duty; soft-off: 45° at 100% duty - reduces mechanical vibration and acoustic noise during fan startup/shutdown. |
| FG/RD Output | Open-drain, Hall-derived speed signal or rotor lock fault indication - requires external pull-up; supports 100% or 50% frequency division for flexible tachometer resolution. |
| Thermal Protection | 150 °C shutdown with automatic recovery - prevents permanent damage during stall or overload; hysteresis ensures stable restart after cooling. |
Pinout & Package
MP6650GJS-0000-P is housed in a TSOT23-6-SL package: 6-pin, 1.6 mm × 2.9 mm, 0.95 mm height, lead-free, RoHS-compliant surface-mount package with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power ground reference | Common return path for motor current, Hall sensor, and internal LDO; must be low-impedance connection to minimize noise coupling. |
| 2 VCC | Main power input | Supplies internal circuitry and gate drivers; accepts 3.3–18 V with reverse-voltage protection; requires local 1 µF ceramic decoupling capacitor. |
| 3 FG/RD | Open-drain status output | Outputs Hall-based tachometer signal (FG) or rotor lock fault (RD); requires external pull-up resistor; active-low RD indicates stalled condition. |
| 4 PWM | Speed control input | PWM interface (2–100 kHz) with internal 41–50 kΩ pull-up; duty cycle directly maps to motor speed; supports soft-start timing configuration (2.6 s or 5.2 s). |
| 5 OUT2 | Motor phase output 2 | Mid-point of internal N-channel half-bridge; connects to one motor winding terminal; switches synchronously with OUT1 under Hall-commutated control. |
| 6 OUT1 | Motor phase output 1 | Mid-point of internal N-channel half-bridge; connects to second motor winding terminal; complements OUT2 to generate rotating field for single-phase BLDC operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Hall sensor | High-sensitivity (±1–2 mT operate point) monolithic Hall cell eliminates external sensor placement and alignment complexity in fan modules. |
| Soft on/off phase transition | Programmable 22.5°–45° angular ramping reduces torque ripple and acoustic noise during fan acceleration/deceleration. |
| Automatic phase-lock detection | Synchronizes switching edges to winding BEMF zero-crossing without external timing components, improving efficiency and stability across load/temperature. |
| Configurable speed vs. duty curve | 14H register sets PWM starting threshold (e.g., 12.5%); 00h–08h lookup table defines full-speed mapping - enables custom fan profiles for thermal management. |
| Input reverse-voltage protection | Shuts down internal circuitry when VCC is reversed (down to −18 V), protecting against assembly errors without external diode or fuse. |
| Programmable overload current limit | Four selectable thresholds (0.7/1.1/1.6/2 A) via SUCL bits allow precise trade-off between motor torque, MOSFET thermal margin, and acoustic performance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP6651GJS-0000-P | Same pinout and package; adds I²C interface for register read/write and enhanced diagnostics (e.g., real-time current monitoring). | Required where firmware-controlled parameter tuning (e.g., dynamic speed curve update) or health monitoring beyond FG/RD is needed. | Select MP6651 if system-level software integration and diagnostic visibility outweigh cost and complexity of adding I²C routing. |
| TB67H401FNG | External Hall sensor required; higher RDS(on) (1.2 Ω total); no integrated reverse-voltage protection; larger HTSOP-J8 package. | Suitable for cost-sensitive designs where board space is less constrained and external protection components are acceptable. | Choose TB67H401FNG only if legacy design reuse or dual-supply operation (up to 40 V) is mandatory; MP6650GJS offers superior integration and noise performance. |
Compared with MP6651GJS-0000-P, MP6650GJS-0000-P trades I²C configurability for lower BOM count and simpler layout; versus TB67H401FNG, it delivers tighter thermal control, smaller footprint, and built-in protection - making it optimal for space-constrained, high-reliability fan applications.

FAQ
What is the function of the FG/RD pin on MP6650GJS-0000-P?
The FG/RD pin is an open-drain output that serves dual roles: when configured for FG mode, it outputs a Hall-derived tachometer signal (100% or 50% of Hall frequency) for speed monitoring; when configured for RD mode, it asserts low to indicate rotor lock after 0.6 s of no Hall edge detection. External pull-up is mandatory, and register 0x0A controls mode selection.
Does MP6650GJS-0000-P require external MOSFETs?
No. MP6650GJS-0000-P integrates a complete N-channel half-bridge with total RDS(on) of 740 mΩ (480 mΩ HS-FET + 260 mΩ LS-FET at 25 °C). It drives single-phase BLDC motors directly without external power switches, reducing solution size and component count.
How is the PWM input frequency range specified, and what happens outside it?
The recommended PWM input frequency range is 2 kHz to 100 kHz. Within this range, the device accurately translates duty cycle to motor speed. Below 2 kHz, speed regulation becomes unstable due to insufficient sampling; above 100 kHz, internal timing resolution degrades, potentially causing erratic commutation or missed edges.
Can MP6650GJS-0000-P drive motors requiring >2 A continuous current?
No. The absolute maximum output current is 2 A (typical limit per electrical characteristics), with over-current protection triggering at 3 A. For higher-current motors, use parallel MP6650 devices only if thermally derated, or select a higher-current driver like MP6651GJS with identical pinout but extended thermal design margin.
What package variant does MP6650GJS-0000-P use, and how does it differ from MP6650GJL?
MP6650GJS-0000-P uses the TSOT23-6-SL package: "SL" denotes standard leadframe orientation with pin 1 at lower-left (same as TSOT23-6-L), but with different top marking (BGK prefix) and tape/reel coding. It is not pin-compatible with TSOT23-6-R or TSOT23-6-RSL variants due to reversed pin 1 location.
Is the Hall sensor position fixed, and can it be calibrated?
Yes. The Hall sensor cell is fixed at (540 µm, 508 µm, 80 µm) from the package corner (per Figure 8); no user calibration is possible. Its sensitivity (±1–2 mT operate point) and hysteresis (2–4 mT) are factory-trimmed and guaranteed over temperature, enabling plug-and-play integration with standard BLDC fan magnets.
How does the soft on/off feature reduce audible noise?
Soft on/off gradually ramps motor current over 22.5°–45° electrical angle instead of abrupt switching, suppressing high-frequency harmonics and mechanical resonance in fan blades and mounts. This reduces broadband acoustic noise by 5–8 dB(A) compared to hard-switched operation, especially during startup and shutdown transients.
